FAN7390 Rev. 1.0.3
The FAN7390 is a monolithic high- and low-side gate-
drive IC, which can drive high speed MOSFETs and
IGBTs that operate up to +600V. It has a buffered output
stage with all NMOS transistors designed for high pulse
current driving capability and minimum cross-conduction.
Fairchild’s high-voltage process and common-mode
noise canceling techniques provide stable operation of
the high-side driver under high dv/dt noise circumstances.
An advanced level shift circuit offers high-side gate driver
operation up to V
=-9.8V (typical) for V
The UVLO circuit prevents malfunction when V
are lower than the specified threshold voltage.
The high current and low output voltage drop feature
make this device suitable for the PDP sustain pulse
driver, motor driver, switching power supply, and high-
power DC-DC converter applications.
